6.5 DHCP Server

6.5.1 Introduction

Dynamic Host Configuration Protocol (DHCP) refers to assigning IP address configurations
dynamically for users on the TCP/IP network. It is based on BOOTP (Bootstrap Protocol)
protocol, and automatically adds the specified available network address, network address re-
use, and other extended configuration options over BOOTP protocol.
With the enlargement of network scale and development of network complexity, the number
of PCs on a network usually exceeds the maximum number of distributable IP addresses.
Meanwhile, the widely use of laptops and wireless networks lead to frequent change of PC
positions and also related IP addresses must be updated frequently. As a result, network
configurations become more and more complex. DHCP is developed to solve these problems.
DHCP adopts client/server communication mode. A client applies configuration to the server
(including IP address, subnet mask, and default gateway), and the server replies with an IP
address for the client and other related configurations to implement dynamic configurations of
IP address.
In DHCP Client/Server communication mode, a specific host is configured to assign IP
addresses, and send network configurations to related hosts. The host is called the DHCP
server.
DHCP application
Under normal circumstances, use the DHCP server to assign IP addresses in following
situations:

Raisecom(config)#interface
interface-number
Raisecom(config-gigaethernet1/1/port)#ipv6
dhcp option
hex-string
hex
No. Command
Raisecom#show ip dhcp
information option
Raisecom#show ip dhcp
option port vlan
description
The network scale is large. It requires much workload for manual configurations, and is
difficult to manage the entire network intensively.
